Reaction Steps

A mixture of 85 mg (0.21 mmol) of 3-[3-tert-butoxycarbonylamino-4-(4-methyl-piperidin-1-yl)-4-oxo-butyl]-benzoic acid, 81 mg (0.42 mmol) of EDC, 57 mg (0.42 mmol), and 2.6 mg (0.021 mmol) of DMAP is stirred in DMF for 2 h at rt. After cooling to −40° C. ˜0.2 mL of NH3 is condensed into the mixture. The resulting solution is sealed and stirred at rt for 10 h. The mixture is concentrated and purified by preparatory TLC (10% MeOH in CH2Cl2) to provide 66 mg (78%) of [3-(3-carbamoyl-phenyl)-1-(4-methyl-piperidine-1-carbonyl)-propyl]-carbamic acid tert-butyl ester.
